Provenance registry

A permanent record for every important stone

Our registry ties a stone's GIA report to the physical stone, and keeps its history, custody and ownership in one place on the Hedera network. Anyone can check a record. No one can quietly change it.

What each record holds

Registry record

GIA report
Report number, and its finding that the color is natural
Inscription
The laser inscription, where there is one, matched to the report
History
Auction results, named-stone records, mine-of-origin papers such as Argyle certificates, and past owners who agree to be listed
Custody
Vault, insurer, and the date of the last physical inspection
Ownership
Who holds the stone, or its shares if it has been offered

How it works on Hedera

  • Each event (registration, inspection, transfer, new report) is written as a time-stamped message on Hedera Consensus Service.
  • Each stone gets one registry token on Hedera Token Service.
  • Documents and personal data stay off the ledger. Only their digital fingerprints go on it, so a record can be checked without exposing the owner.

We don't grade stones. We rely on GIA's reports, and connect them to the stone and its story.

Register a stone

Registration and verification fees: [pricing]. Registering a stone isn't an investment, and it doesn't commit you to offering the stone.
